"But my advice to him is not about national teams, my advice is to keep the way he is, which is very humble, very open to learn, intelligent, and to keep going in the same direction, with the same profile, trying to fight to have minutes with Manchester United, which is not easy, and then national team will be just a consequence of his work at the club.

"But I can't confirm at all that both national teams have contacted him."

Mourinho praised the way McTominay has slotted into the United team and added: "I think it's a consequence of his profile as a boy and I think the people around him are the right people.

"I never met them, but I have to believe the kid with his attitude towards the others and towards football, I believe the parents must be really good people, who have passed to him the right values.

"The kid has his feet on the ground, he's very calm, and I think he passed some important tests not by the football point of view, but the mental point of view.

"He has maturity, he's calm, he can play against champions, play knockout in the Champions League, and pass those two tests by the mental approach, so I think a long way to go, obviously, but he has his feet on the ground, he's very stable and I hope he can keep the same image."
